**What it does**

Creates an interactive Krona_ chart of taxonomic abundance. Requires a KronaTools installation (2.0 or higher) with taxonomy downloaded.

 .. _Krona: http://krona.sourceforge.net

**Inputs**

The inputs can be Galaxy taxonomic representations, for example::

  1                     2    3    4         5       6 7 8        9        10            11       12 13               14       15         16          17        18  19  20 21  22  23           24 25
  1L_EYKX4VC01BXWX1_265 9606 root Eukaryota Metazoa n n Chordata Craniata Gnathostomata Mammalia n  Euarchontoglires Primates Haplorrhini Hominoidea Hominidae n   n   n  Homo n  Homo sapiens n  1430919

...or, they can be tabular BLAST results containing gi numbers, which will be used to look up taxonomy IDs and find lowest common ancestors for best hits (comment lines are optional but required for showing queries with no hits in the chart)::

  1      2                            3      4    5  6  7  8    9        10       11     12
  read1  gi|211853080|gb|EQ846228.1|  97.33  150  1  3  6  154  9518999  9519146  5e-64  252
  read2  gi|211853080|gb|EQ846228.1|  96.69  151  0  5  6  154  9496147  9496294  2e-62  246

...or, they can be lists of taxonomy IDs preceded by query IDs or counts (these formats can be exported by ktClassifyBLAST or MEGAN), but **Summarized** must be checked if they are counts::

  1	    2
  read1 9606
  read2 9616

Summarized::

  1     2
  243   9606
  17    9616

Both forms can optionally have scores::

  1     2    3
  read1 9606 94.34
  read2 9616 32.17

Summarized::
  
  1     2    3
  243   9606 94.34
  17    9616 32.17
